Answer:
2 and 4
Step-by-step explanation:
The domain is the set of x-values of a function. The range is the set of y-values of a function.
You are told that the domain, or x-values, are -8, -6, -3, -2, and 2. To find the range, you just need to plug in each of the x-values into the function <span>y = -3x + 7 and find the value of y.
1) When x = -8:
</span><span>y = -3x + 7
y = -3(-8) + 7
y = 24 + 7
y = 31
2) When x = -6
</span>y = -3x + 7
y = -3(-6) + 7
y = 18 + 7
y = 25
3) When x = -3
y = -3x + 7
y = -3(-3) + 7
y = 9 + 7
y = 16
4) When x = -2
y = -3x + 7
y = -3(-2) + 7
y = 6 + 7
y = 13
5) When y = 2
y = -3x + 7
y = -3(2) + 7
y = -6 + 7
y = 1
The range is {31, 25, 16, 13, 1}.

Answer: {31, 25, 16, 13, 1}
Answer:
not a solution
Step-by-step explanation:
y < 7x + 8
Substitute (2-,-6) into the inequality
-6 < 7(-2) +8
-6 <-14+8
-6 <-6
This is not true because they are equal not less than
Answer:
c. there are 4 fewer sixth graders than eighth graders who would prefer the same amount of time between classes.
Step-by-step explanation:
